Football is a team sport played by two teams that compete to score more goals than their opponents. At the end of the game, the team with the most goals wins. It is one of the most popular games around the world. It is played for several reasons, including recreation, competition, and health. Here are some basic rules.
First, the football must be round. Its circumference is set by FIFA specifications. Most footballs are made of leather, synthetic, or composite material. They are inflated to appropriate pressure for kicking. Other basic rules of football include: competition must consist of two teams with a maximum of eleven players. Each team must have a goalkeeper. In addition, the winning team is allowed to choose the direction of play.
Second, football is dangerous when tackled incorrectly. Incorrect tackles are known as targeting. The NCAA defines targeting as “forcible contact with the head or neck of a defenseless player.” This rule prohibits leading with the crown of the helmet during a tackle.
